VB写的串口通讯软件，简单易学，适合初学者(Written in VB serial communication software, is easy to learn)

说明：  自动识别电脑有多少个串口，关自动加载!!!(Automatically identify the number of serial computer, turn off automatic loading )

读取串口调试助手保存的TXT文档，将连续两个8位合并为一个16位数据，然后进行图形化显示，分析了幅频特性，然后对其进行了低通滤波并画图(Read the serial debugging assistant TXT files saved in the continuous two 8 into a 16-bit data, and then graphically analyzed amplitude-frequency characteristics, and its low-pass filtering and drawing)

RS232的UART编程，包括波特率发生器模块，串口接受模块，串口发送模块(RS232 programming the UART, including the baud rate generator module, serial module to receive, send serial module)

包含串口测试程序。和串口向PC机发送字符的程序。(Contains serial port test program. And serial port to send characters to the PC program.)

matlab串口m文件，很不错(m file matlab serial, very good)

485多机通讯的连接方式，主要有总线方式、星形方式等(connection of multi pc communication with 485)

托利多地磅仪表读取，通信用串口mscomm做的(Toledo floor scale meter reading, communications, made with a serial mscomm)

从事Profibus的开发人员可以利用改源代码理解profibus协议。添加除通讯以外的代码，很快可以开发出自己的智能节点(engaged in the development staff can use the source code to understand change Profibus agreement. Add except communications code, we will soon be able to develop their own intelligent nodes)

这个程序是利用VC编写的一个从机串口响应modbus查询命令程序，实现RTU方式，3.5和1.5个字符时间检测，CRC和LRC校验。(This program is written using VC as a response from the machine serial modbus query command procedure, to achieve RTU mode, 3.5 and 1.5 characters time detection, CRC and LRC check.)
